Hi, it appears that I have a completely dead TZ clock motor - I measured 13V DC going to the motor on game power-on, the clock gear assembly spins with minimal resistance by hand with the motor removed, and there's no pinion movement when the motor's connected to a 9V battery. Therefore, I'm in the market for a new motor.

Does anybody know the specs on the motor, specifically the RPM? I see there are a replacements available via pin parts suppliers, but I would think a standard 12V DC motor with the same specs would work at a lower cost. Thanks!

Certainly worth exploring too. The armature isn't locked up and spins freely, so perhaps the magnets are just shot. Might be a hassle to find magnets that fit though (I'm not well-versed in DC motors though, so maybe not!).

Yes sorry, I meant maybe the brushes are worn out. The symptoms actually began as the motor getting slower and slower over time when I'd power the game on, and now there's zero movement. I'll see if I can open it up to take a look.
